All 30 MLB Teams Ranked by Bullpen Strength: 2026 Season

Which Teams Have the Best Bullpens in MLB?

The elite tier converts leads into wins at a rate that makes their moneyline prices more reliable than they look in close games. These are the teams where a one-run lead in the seventh inning is genuinely meaningful.

Atlanta Braves have one of the best bullpens in baseball heading into 2026. Their back-end duo of Raisel Iglesias and Ranger Suarez — the NL saves leader — makes the eighth and ninth inning a legitimate strength rather than a liability. A projected 3.91 ERA tied for fourth in MLB backs up the talent evaluation. The Braves retained Iglesias and Kinley while adding Suarez in a clear signal that the front office prioritized bullpen quality as a competitive advantage. When Atlanta takes a lead into the seventh inning, you can bet their win probability with real confidence.

Los Angeles Dodgers combine rotation depth with a bullpen that consistently ranks in the S and A tiers across case-study and tier-list analyses. Multiple high-leverage arms, swing-and-miss ability throughout the pen, and smart roster construction make their relief corps one of the strongest combinations of depth and quality in the league.

New York Mets join the Dodgers and Braves in the elite NL tier, with a pen that balances swing-and-miss relievers with length options that can cover innings without blowing leads. Their back-end construction is one of the cleaner builds in the league.

Other bullpens consistently appearing in the elite tier:

• Teams with established closers posting sub-3.00 ERAs over recent seasons and clear eight-inning setup options behind them
• Pens with multiple high-leverage arms rather than relying on a single closer to carry everything

Which Teams Have Solid but Not Elite Bullpens?

These pens are reliable in most spots but have enough uncertainty — usually in the middle relief or depth roles — to make them situational rather than automatic.

• Chicago Cubs: One strong closer with a capable setup option behind him, then a mix of young arms that create some inning-specific variance.
• Cleveland Guardians: Middle-of-the-pack projected ERA with a clear back-end option and less certainty in the bridge roles.
• Arizona Diamondbacks: Competitive pen with one or two reliable high-leverage arms and depth that can be exposed in a short series.
• Toronto Blue Jays: Capable closer with decent setup options, but the depth behind the top two or three arms creates game-by-game variance worth noting.
• Tampa Bay Rays: Well-coached pen that historically outperforms their individual talent level. Their bullpen management approach keeps them competitive even when the individual arms are below elite.
• Miami Marlins: Lost a key reliever to injury but added Pete Fairbanks — 75 saves and a 2.98 ERA over three seasons — to stabilize the back end. On paper they're competitive, but depth behind the top two arms is thinner than you'd want for a team relying heavily on their pen.

For betting, these pens are worth respecting in late-inning moneyline spots when their top arms are available. They become more vulnerable in back-to-back high-leverage situations where depth gets tested.

Which Teams Have Average or Below-Average Bullpens?

These pens convert leads at an average rate and lose games they probably shouldn't at a higher clip than the elite tier. Factor them into your live betting and late-inning moneyline decisions.

• Baltimore Orioles: Solid enough when healthy but with the kind of depth questions that show up in July and August when the pen gets taxed.
• Houston Astros: Not what they were in peak years. Their bullpen construction has more questions than in previous seasons, particularly in bridge roles.
• San Francisco Giants: Middle-tier pen without the back-end firepower to inspire confidence in one-run game situations.
• Minnesota Twins: Average projected ERA with a clear closer but real uncertainty in the setup roles behind him.
• Boston Red Sox: The rotation is their strength. The bullpen is competent but not a reason to pay up on moneyline prices in close games.
• Milwaukee Brewers: Well-managed pen that squeezes value from the roster, but the individual talent level sits in the middle tier of the league.

Which Teams Have the Worst Bullpens in MLB?

These pens are active liabilities. Late-inning leads are never fully safe, and live betting value exists regularly in games where these teams are protecting small advantages.

Washington Nationals had the worst bullpen ERA in MLB in 2025 at 5.59, and FanGraphs projects them for the third-worst ERA and the lowest fWAR in 2026. Their young corps of Carl Beeter, Cole Henry, and Cole Rutledge is more future trade bait than present competitive strength. Betting against the Nationals bullpen in close games is one of the most consistent live betting edges in the sport.

Colorado Rockies compound their bullpen problems with the altitude factor at Coors Field. Their relief ERA inflates in ways that make opponent run scoring in the late innings genuinely unpredictable. Over bets in Rockies home games involving their bullpen are among the strongest recurring situations in baseball totals markets.

Other bottom-tier groups projecting near the bottom of relief WAR and ERA tables:

• Deep rebuild teams where relievers are young arms in development rather than proven contributors
• Teams where the closer role is unsettled and multiple options are competing for high-leverage innings

How Bullpen Rankings Should Change Your MLB Bets

The practical application of bullpen tiers shows up in specific betting situations every single day.

• Live moneyline betting: If a team with an elite bullpen takes a one-run lead into the seventh inning, their live win probability is worth backing even at shortened odds. If a team with a bottom-tier bullpen takes the same lead, the live market is often overpricing their win probability.
• Totals betting: Weak bullpens push games toward the over in the late innings. Strong bullpens push games toward the under. When both starters leave before the sixth inning and two bottom-tier pens are matching up, the over becomes significantly more attractive.
• Series betting: Bullpen quality compounds over three games in ways that single-game moneylines don't fully capture. A team with an elite bullpen in a three-game series against a weak-pen opponent should be backed more aggressively on series prices than their individual game lines suggest.
• Closer availability: Bullpen ratings assume normal availability. After back-to-back saves opportunities, even elite pens become average. Check usage before betting late-inning moneylines on any team in their third game of a series.
